InvitedPaper presented at conference/seminar on difficult fieldwork, discusses compromises that ethnographers will have to make as their fieldwork becomes more fragmented and their study objects more suspicious, especially when studying elites; the possibility of any solidarity or empathy with the people we study may be declining.
Current corporate governance recommendations – rooted in an investor-based shareholder supremacy model – often narrowly discuss the issue of board leadership as whether or not there is a separation of the CEO and chairperson positions. In this article we employ a team production approach to better understand the leadership role of the board chairperson. We argue that effective board performance is
This paper presents a development of the use of multi-axial ultrasonic data for the quantification of extrinsic, crack or grain-contact induced elastic anisotropy in core samples with application to a UKCS oil field. An approach for inversion of multi-axial velocity measurements is presented, which extends the previous work by Sayers (2002) for the determination of second- and fourth-order crack d
We investigate the magnetic instabilities of the nondegenerate (s-band) and a degenerate (d-band) Hubbard model in two dimensions using many-body effects due to particle-particle diagrams and Hund’s rule local correlations. The density of states and the position of the Van Hove singularity change depending on the value of next-nearest-neighbor hopping t′. The Stoner parameter is strongly reduced i
These days more and more software is produced as product families. Products that have a lot in common, but all the same vary slightly in one or more aspects. Developing and maintaining these product families is a complex task. Software configuration management (SCM) can, in general, support the development and evolution of one single software product and to some degree also supports the concept of
Whatever their size and the ecosystem they live in, all organisms may disperse at some stage of their life cycle. Dispersal dynamics are to a varying extent dependent on organismal size, life history, ecological niche, survival capacities and phylogeny. Moves towards a synthesis in dispersal ecology have focused primarily on vertebrates and higher plants, yet recent studies suggest that the disper
